How do I disable caching when opening a NetCDF file with xarray in Python, ensuring that the most up-to-date data is always accessed?

To disable caching when opening a NetCDF file with xarray in Python, you can use the cache parameter in the open_dataset function and set it to False. This ensures that xarray does not cache the data and always accesses the most up-to-date data from the file.

import xarray as xr

Open the NetCDF file with caching disabled

dataset = xr.open_dataset('path_to_your_file.nc', cache=False)

Access your data

print(dataset)

Explanation cache=False: Setting this parameter to False ensures that xarray does not cache the data, and each access to the dataset reads the most current data directly from the file.

By using the cache=False parameter, you can disable caching and ensure that your xarray dataset always reflects the most recent data.
